A colostomy is a surgical procedure that brings a portion of the large intestine through the abdominal wall to carry feces out of the body.
A colostomy is a means to treat various disorders of the large intestine, including cancer, obstruction, inflammatory bowel disease, ruptured diverticulum, ischemia (compromised blood supply), or traumatic injury.
Temporary colostomies are created to divert stool from injured or diseased portions of the large intestine, allowing rest and healing.
Permanent colostomies are performed when the distal bowel (at the farthest distance) must be removed or is blocked and inoperable.
Although colorectal cancer is the most common indication for a permanent colostomy, only about 10-15% of patients with this diagnosis require a colostomy.
